Imaging of the Shoulder Bankart Lesion and its Variants

Abstract

The glenoid labrum is an important soft tissue structure that provides stability to the shoulder joint. When the labrum is injured, affected patients may present with chronic shoulder instability and future recurrent dislocation. The Bankart lesion is the most common labral injury, and is often accompanied by a Hill-Sachs lesion of the humerus. Various imaging techniques are available for detection of the Bankart lesion and its variants, such as anterior labroligamentous periosteal sleeve avulsion and Perthes lesion. Direct magnetic resonance (MR) arthrography is currently the imaging modality of choice for evaluation of the various types of labral tears. As normal anatomical variants of glenoid labrum are not uncommonly encountered, familiarity with appearances of this potential pitfall helps avoid misdiagnosis.

Recurrent shoulder dislocation treated with Bristow Latarjet procedure: a case report

“…With its superior soft-tissue resolution, the glenoid labrum is best studied using proton density fat-suppressed or fluid-sensitive fat-suppressed sequences in the oblique coronal and axial planes on conventional MR imaging without arthrography. 8 The BL procedure is a well-known surgical technique designed to treat shoulder instability. In this procedure, the coracoid process is transferred to the glenoid rim to augment an associated bony defect.…”
